Difference Between Reactive Dyed and Vat Dyed Fabrics
Choosing the right type of dyes can help you achieve the right performance at the right price.
Reactive dyed and vat dyed fabrics are two types of fabrics that are dyed with different types of dyes and methods. Here are some of the differences between them:
- Reactive dyed fabrics can offer more variety and appeal to the end consumer, as they have a wide range of bright and vibrant colors. Vat dyed fabrics can be more durable and reliable for the end consumer, as they have excellent fastness properties and resist fading or staining.
- Reactive dyed fabrics can be more cost-effective as they have lower production costs and less environmental impact. Vat dyed fabrics can be more expensive as they have higher production costs and more environmental impact.
- Reactive dyed fabrics can be more fashionable and trendy as they can follow the latest color trends and create unique designs. Vat dyed fabrics can be more classic and timeless as they can create solid and even shades of color or use resist dye techniques such as tie-dyeing.
- Reactive dye is a water-soluble dye that forms a covalent bond with the fiber, making it an integral part of the fiber. Vat dye is a water-insoluble dye that requires a reduction and oxidation process to be applied to the fiber.
- Reactive dye is mainly used for cellulosic fibers such as cotton, rayon, and linen. Vat dye can be used for cellulosic fibers as well as synthetic fibers such as polyester and nylon.
- Reactive dye has very good lightfastness and washfastness, but moderate rubbing fastness. Vat dye has excellent all-round fastness properties that are unmatched by other dyes
- Reactive dyeing is carried out in an alkaline medium and involves three steps: exhaustion, fixation, and washing off. Vat dyeing is also carried out in an alkaline medium and involves three steps: vatting, dyeing, and oxidation
